DUPLEX BRAIDER.

Specification of Letters Patent.

Patented Nov. 24, 1914.

bular braiding machine comprising lowcr-` deck and upper-deck braiders having coop eratlng carrier courses, as fully described 1n connection with'the accompanying drawings and the novel features of which are specificall pointed out in the claims.

4igure 1 is a front elevation of my iinproved machine, indicating the essential features thereof. Fig. 2 is a similar end elevation. Figs. 3 and/1 are plan views of the is a diagrammatic View indicating the cooperative arrangement of the several courses andthe character of the product produced.

The lower-deck braider is provided, as shown, with separate circular courses, 2 and 2 respectively, formed as usual in the upper plate 3 thereof; and with separate series of carriers, 4 and 4 respectively (Fig. 1), which are4 operated by carrier gears arranged as usual between the upper plate 3 and lower plate 5. A core-way, (i or 6, is provided at the center of each course; through which may be fed a core wire, 7 or 7 (Fig. 5), upon which the carrier threads of the separate courses are brought together. at braiding points 8 or 8". i

`The upper-deck braider, which is mounted upon standards 10 on the lower braider, is similarly constructed, but provided only with a single carrier course, l1, having its center midway between the lower-deck courses; the combined products of the lower braider being passed thereto as hereinafter described. The carrier drive gears of thc upper-deck course 11, are driven jointly with those of the lower-deck courses as shown, through a vertical shaft l5 carrying a gear 16, and through an idler gear i7 in mesh with the series of carrier gears; and this. idler gear is adjustablv mounted in a slot 18 of the plate so that the size of the gear 17 may be adapted to produce any desired speed of the upper-deck carriers relative to those ofthe lowercourses though all are driven from the belt wheel 19.

As indicated in Fig. 5 the separate core wires 7, 7 are covered by the braidingl of the two lower-deck carrier courses, and are carried upward through the guide tubes 27, 27 and jointly covered by the braiding of the single upper carrier course. The final product is carried over the take-oil' pulley 420 to a takeoff drum (not shown), which latter is driven in coperation with all the carriers as indicated; the belt wheel 21 for said drinn being fixed to the transverse shaft 22 which is rotated with the` carrier gears through the vertical worin shaft Qlland gear wheels Q4, 25, and E2G. Convcrging guidetubes 27, 2 1, are provided for the separate braidings of the lower decir carrier courses; these being carried upon a suitably fixed cross-bar 28 having separate braiding-point passage ways 29, 29", for said braidings, and the guide-tubes '27, Q7, passing through the plates of the upper-deck braider and con verging to a point below the fixed braidingpoint guide 30 of the latter.

lt will be seen that the take-oil' drive wheel 20,is driven at a fixed speed relative to the carriers of the lower braiding courses, while the speed of the carriers of the upperdeck course may be varied so as to provide for varying the closeness of the covering braiding formed by the upper-deck carrier course independently of the fixed relation of the latter to the take-otl` and lower-deck carrier courses. The several braidings are simultaneously formed and combined to pro v ide a compound product suitable. for varions purposes.
